QCA570
Based on 1 Customer Validation
QCA570 is a pan-BET-BRD PROTAC degrader. QCA570 degrades BRD2/3/4 and BRDT via cereblon and the ubiquitin-proteasome pathway, inhibits the expression of c-MYC, EZH2 and Mcl-1, induces tumor cell apoptosis, cycle arrest and regression, and exerts a synergistic inhibitory effect on Osimertinib (HY-15772)-resistant EGFR-mutant non-small cell lung cancer. QCA570 can be used in the research of acute myeloid leukemia, acute lymphoblastic leukemia, bladder cancer and non-small cell lung cancer.

QCA570 (compound 35) (for 4 days) potently inhibits the growth of MV4;11, MOLM-13 and RS4;11 human acute leukemia cells, with IC50 values of 8.3 pM, 62 pM and 32 pM, respectively[1].
QCA570 (30 pM) degrades all BET-BRD proteins in RS4;11 leukemia cells and inhibits the growth of RS4;11 cells with an IC50 of 50 pM[4].
QCA570 (4 h) degrades BRD4 and inhibits c-MYC in CD34-enriched leukemic stem cells from primary AML samples[4].
QCA570 (0.01-10 nM; 3 h) potently induces the degradation of BRD2, BRD3 and BRD4 proteins at picomolar concentrations and suppresses c-Myc protein levels in MV4;11 and RS4;11 human acute leukemia cells after 3 hours of incubation[1].
QCA570 (0.5 nM; 3 h) induces the degradation of BRD2, BRD3 and BRD4 proteins in RS4;11 human acute leukemia cells via cereblon-dependent, neddylation-dependent and proteasome-dependent mechanisms, with no effect on GSPT1 protein levels[1].
QCA570 (0.01-100 nM; 9 h) potently induces proteasome-dependent degradation of BRD2, BRD3 and BRD4 proteins in 5637, J82, T24, UM-UC-3 and EJ-1 human bladder cancer cells[2].
QCA570 (10-100 nM) inhibits the expression of BRD4 target genes c-MYC and EZH2 at both mRNA and protein levels in human bladder cancer J82, T24 and 5637 cells[2].
QCA570 (72 h) potently inhibits the proliferation of 5637, J82, T24, UM-UC-3 and EJ-1 human bladder cancer cells, with IC50 values ranging from 2.68 to 30.44 nM[2].
QCA570 potently reduces the viability of human non-small cell lung cancer cell lines (H1975, H157, Calu-1, H1299, H1650, H460, H1792, PC-9, EKVX, H1944), with IC50 values ranging from 0.3 nM to 100 nM, and its sensitivity correlates with higher baseline BET protein levels[3].
QCA570 potently inhibits the proliferation of MV4;11 cells, with an IC50 of 0.0083 nM[5].
QCA570 exhibits no toxicity to normal CD34-positive hematopoietic cells in apoptosis assays and colony formation assays[4].
QCA570 (0.01-10 nM; 24-48 h) potently induces apoptosis in human acute leukemia cell lines MV4;11, MOLM-13 and RS4;11 in a dose- and time-dependent manner, with faster apoptotic kinetics observed in MV4;11 and MOLM-13 cells than in RS4;11 cells[1].
QCA570 (0.1-0.3 nM; 24 h) induces PARP cleavage in human acute leukemia cells MV4;11 and RS4;11 at picomolar concentrations. After 24 h of treatment, caspase 3 activation is detectable in MV4;11 cells, but this phenomenon is not observed in RS4;11 cells at the same time point[1].
QCA570 (10-100 nM; 72 h) induces dose-dependent apoptosis in 5637, J82, T24, UM-UC-3 and EJ-1 human bladder cancer cells, as detected by Annexin V-FITC/PI staining, activated caspase-3 expression assay and TUNEL staining[2].
QCA570 (5-10 nM; 24 h) induces apoptosis in human non-small cell lung cancer cell lines (H157, H1975, H1650, Calu-1), where downregulation of Mcl-1 plays a key mediating role, while Bim is dispensable for this activity[3].
QCA570 (1-10 nM; 7 h) potently and rapidly reduces the levels of BRD4, BRD3, BRD2, Mcl-1 and Bim in human non-small cell lung cancer cell lines (H157, H1975, Calu-1) at concentrations as low as 1 nM, and exerts cell-specific effects on c-Myc levels[3].
QCA570 (0.3125-30 nM; 3 days, 36-72 h, every 3 days for 12 days) acts synergistically with Osimertinib (HY-15772) to reduce cell viability, induce apoptosis, and inhibit colony formation in Osimertinib-resistant human EGFR-mutant non-small cell lung cancer cell lines (PC-9/AR, PC-9/GR/AR, HCC827/AR)[3].
Combination treatment with QCA570 (1 nM; 12 h) and Osimertinib exerts a synergistic apoptosis-inducing effect in Osimertinib-resistant human EGFR-mutant non-small cell lung cancer cell lines (PC-9/AR, PC-9/GR/AR, HCC827/AR), and this effect is mainly mediated by enhanced Mcl-1 degradation[3].
QCA570 (10 nM; 72 h) induces G2/M phase cell cycle arrest in human bladder cancer 5637 cells[2].
QCA570 (100 nM; 8-48 h) inhibits the migration of human bladder cancer cell lines 5637, EJ-1, J82 and T24[2].
